Lub luag haujlwm ntawmCMC (Carboxymethyl Cellulose) Nyob rau hauv ceramic glazes yog feem ntau xav txog nyob rau hauv cov nram qab no yam: thickening, bonding, dispersion, txhim kho txheej kev ua tau zoo, tswj glaze zoo, thiab lwm yam. Raws li ib tug tseem ceeb natural polymer tshuaj, nws yog dav siv nyob rau hauv kev npaj ntawm ceramic glazes thiab ceramic slurries.
1. Thickening nyhuv
CMC yog cov dej-soluble polymer compound uas tuaj yeem tsim cov kua dej khov hauv dej. Qhov no feature ua rau nws lub luag hauj lwm nyob rau hauv ceramic glazes tshwj xeeb tshaj yog tseem ceeb, tshwj xeeb tshaj yog thaum lub viscosity ntawm glaze yuav tsum tau kho. Ceramic glazes feem ntau yog tsim los ntawm inorganic hmoov, iav yav dhau los, fluxing agents, thiab lwm yam. Kev sib ntxiv ntawm cov dej qee zaum ua rau cov glaze muaj fluidity ntau dhau, ua rau cov txheej tsis sib xws. CMC tsub kom lub viscosity ntawm glaze, ua rau lub glaze txheej zoo ib yam, txo cov fluidity ntawm glaze, yog li txhim kho daim ntawv thov nyhuv ntawm glaze thiab zam teeb meem xws li glaze zawv zawg thiab dripping.
2. Bonding kev ua tau zoo
Tom qab ntxiv CMC rau ceramic glaze, CMC molecules yuav tsim ib qho kev sib raug zoo nrog cov hmoov inorganic hauv glaze. CMC txhim kho qhov adhesion ntawm glazes los ntawm kev tsim hydrogen bonds nrog dej molecules los ntawm carboxyl pawg hauv nws cov molecules thiab cuam tshuam nrog lwm pawg tshuaj. Qhov kev sib koom ua ke no ua rau cov glaze ua kom zoo dua rau ntawm qhov chaw ntawm cov txheej txheem txheej txheej txheej txheej, txo cov tev thiab ua kom cov txheej txheej, thiab txhim kho kev ruaj ntseg ntawm txheej glaze.
3. Cov nyhuv dispersion
CMC kuj muaj cov nyhuv dispersing zoo. Nyob rau hauv cov txheej txheem ntawm kev npaj ntawm ceramic glazes, tshwj xeeb tshaj yog thaum siv ib co inorganic hmoov nrog cov khoom loj, AnxinCel®CMC tuaj yeem tiv thaiv cov khoom ntawm agglomerating thiab tswj lawv cov dispersibility nyob rau hauv cov dej theem. Cov pawg carboxyl ntawm CMC cov saw hlau molecular cuam tshuam nrog lub ntsej muag ntawm cov khoom, txo cov kev nyiam ntawm cov khoom, yog li txhim kho cov dispersibility thiab stability ntawm glaze. Qhov no yog qhov tseem ceeb heev rau lub uniformity thiab xim sib xws ntawm glaze.
4. Txhim kho txheej txheej
Qhov kev ua tau zoo ntawm cov iav glaze yog qhov tseem ceeb rau qhov zoo ntawm qhov kawg glaze. CMC tuaj yeem txhim kho qhov fluidity ntawm glaze, ua kom yooj yim rau cov txheej txheej ntawm lub cev ceramic. Tsis tas li ntawd, CMC kho cov viscosity thiab rheology ntawm glaze, yog li ntawd lub glaze tuaj yeem ruaj khov rau saum npoo ntawm lub cev thaum kub kub thiab tsis yooj yim rau poob. CMC tseem tuaj yeem txo qhov nro ntawm glazes thiab ua kom muaj kev sib raug zoo ntawm glazes thiab saum npoo ntawm lub cev ntsuab, yog li txhim kho cov dej ntws thiab adhesion ntawm glazes thaum txheej.
5. Tswj glaze zoo
Cov nyhuv kawg ntawm ceramic glazes muaj xws li gloss, flatness, transparency thiab xim ntawm glaze. Qhov sib ntxiv ntawm AnxinCel®CMC tuaj yeem txhim kho cov khoom no kom zoo rau qee yam. Ua ntej, cov nyhuv thickening ntawm CMC tso cai rau lub glaze los tsim ib tug niaj hnub zaj duab xis thaum lub sij hawm firing txheej txheem, tsis txhob muaj teeb meem tshwm sim los ntawm nyias nyias los yog tuab glazes. Qhov thib ob, CMC tuaj yeem tswj cov evaporation tus nqi ntawm cov dej kom tsis txhob ua kom tsis sib xws ntawm cov glaze, yog li txhim kho cov gloss thiab pob tshab ntawm glaze tom qab tua.
6. Txhawb kev tua hluav taws
CMC yuav decompose thiab volatilize ntawm qhov kub thiab txias, thiab cov roj tso tawm tuaj yeem muaj qee yam kev tswj hwm ntawm cov cua thaum lub sij hawm glaze firing txheej txheem. Los ntawm kev kho tus nqi ntawm CMC, kev nthuav dav thiab kev cog lus ntawm cov glaze thaum lub sij hawm tua hluav taws tuaj yeem tswj tau kom tsis txhob muaj cov kab nrib pleb lossis tsis sib xws ntawm qhov glaze nto. Tsis tas li ntawd, qhov sib ntxiv ntawm CMC kuj tseem tuaj yeem pab cov glaze tsim ib qho chaw smoother ntawm qhov kub thiab txias thiab txhim kho qhov zoo ntawm cov khoom siv ceramic.
7. Tus nqi thiab kev tiv thaiv ib puag ncig
Raws li cov khoom siv polymer ntuj, CMC muaj tus nqi qis dua li qee cov tshuaj hluavtaws. Tsis tas li ntawd, txij li CMC yog biodegradable, nws muaj ntau qhov zoo ib puag ncig thaum siv. Hauv kev npaj ntawm ceramic glazes, kev siv CMC tuaj yeem tsis tsuas yog txhim kho cov khoom zoo, tab sis kuj txo cov nqi tsim khoom, uas ua tau raws li cov kev cai ntawm kev tiv thaiv ib puag ncig thiab kev lag luam hauv kev lag luam ceramic niaj hnub.
8. Kev siv dav dav
CMC tuaj yeem siv tsis tau tsuas yog nyob rau hauv tej yam ntuj tso tej hub glazes, tab sis kuj nyob rau hauv tshwj xeeb ceramic khoom. Piv txwv li, nyob rau hauv high-temperature raug rho tawm haujlwm ceramic glazes, CMC tuaj yeem zam qhov tsim ntawm glaze tawg; nyob rau hauv cov khoom siv ceramic uas yuav tsum muaj qhov tshwj xeeb gloss thiab kev ntxhib los mos, CMC tuaj yeem ua kom zoo dua cov rheology thiab txheej txheej ntawm glaze; Hauv kev tsim cov khoom siv kos duab ceramics thiab khoom siv tes ua ceramics, CMC tuaj yeem pab txhim kho qhov muag thiab ci ntawm glaze.
Raws li ib qho ntxiv nrog ntau lub luag haujlwm hauv ceramic glazes, AnxinCel®CMC tau dhau los ua cov khoom siv tseem ceeb hauv kev lag luam ceramic. Nws txhim kho qhov zoo thiab kev ua tau zoo ntawm ceramic glazes los ntawm thickening, bonding, dispersion, thiab txhim kho txheej kev ua tau zoo, uas thaum kawg cuam tshuam rau cov tsos, muaj nuj nqi thiab firing nyhuv ntawm ceramic khoom. Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam ceramic, daim ntawv thov kev cia siab ntawm CMC yuav nthuav dav dua, thiab nws cov kev tiv thaiv ib puag ncig thiab cov nqi qis kuj ua rau nws ua lub luag haujlwm tseem ceeb hauv kev tsim cov ceramic yav tom ntej.
